Decals

How come we cant do bike decals like original really thin they all seem to bit thick with this vinyl or i am wrong

Actually, those narrow fonts are usually done with screen printing or pad printing.
Screen printing is wonderful; many say it's dead, but the quality and depth of screen printing inks just aren't achieved with digital printing. For example, many greens or oranges struggle to turn out well digitally.
That's one of the advantages of UV DTF: if you have a Pantone or RAL or whatever, it gives you the same or very similar color.

And yes, it has some volume; it's not much, but it's noticeable.
But the advantage of being able to make a letter as tiny as the Ritchey one on my pedals and having it fit perfectly makes up for it.

Another detail of this system is that the tone is glossy, and that can complicate some logos.

By the way, if you get a file, you can use it for laser engraving.
I'm planning to do it on a crank.
For now, I've tried doing it on the top of a Ringle headset for my Zaskar, which I gave a USA theme, and I'm honestly very satisfied.
The good thing about laser engraving is that it engraves on paint, metal, plastic... the bad thing is that if you make a mistake or it goes wrong, you've ruined the part.
